EDWARD D. YEATTS, OF SANGER, TEXAS.

CULTIVATOR-STANDARD.

Application filed August 1, 1910.

To all whom 'it may concern.'

Be it known that I, EDWARD D. YEATTS, a citizen of the United States,residing at Sanger, in the county of Denton and State of Texas, haveinvented a new and useful CultivatonS-tandard, of which the following isa specification.A

This invention relates to a cultivator standard and consists in thenovel construe tion and arrangement of its parts as hereinafter shownand described.

The object of the invention is to provide a standard of simple structurewhich may be readily adjusted to pitch or position a cultivator shovelat a desired angle to the line of draft and at a desired angle withrelation to the surface of the soil.

With the above object in view the structure includes a block adapted tobe clamped in position upon a cultivator beam and having a sleevejournaled therein. The sleeve is provided at one end with a worm wheelwhich engages a worm journaled upon the block. A bolt is detachablyinserted in the C sleeve but is restrained against independent rotarymovement with relation to the sleeve. At its outer end the said boltcarries a collar which adjustably receives the upper end portion of astandard to which a cultivator shovel is pivotally attached at its lowerend. In the accompanying drawing z-Figure 1 is a side elevation of thecultivator standard` Fig. 2 is a transverse sectional view through thesupporting block of the standard. Fig. 3 is a sectional view of thecollar forming a part of the standard mechanism. i a horizontalsectional view of the collar.

The standard is adapted to be used in conjunction with a beam indicatedat 1 in the drawings and the standard mechanism includes a block 2having an opening which snugly receives the beam 1 the said bloclr atone side being split as indicated at 3 and having outstanding flanges 4:which are conn neet-ed together by means of clamp bolts 5. Therefore itwill be seen that when the said bolts are tightened and the flanges 4Lare drawn together the block 1 will be firmly clamped in an adjustedposition upon the beam 1. A sleeve 6 is journaled for rotation in theblock 1 and extends transversely with relation to the beam 1. At one endthe sleeve 6 is provided with a worm wheel 7 which meshes with a worm 8journaled be tween lugs 9 located at one of the sides of the block 1.

Fig. 4 is Specification of Letters Patent.

Serial No. 574,756.

I arovided with a projecting non-circular end The shaft of the worm 8 isl 4wheel, a bolt carried by 10 to which a wrench or crank may be appliedfor the purpose of turning the said worm. A non-circular bolt 11 isdetachably located in the sleeve 6 and is snugly received in thenon-circular opening provided in the sleeve and thus the said bolt 11 isrestrained in the sleeve against independent rotary movement withrelation to the sleeve but may rotate in unison with the same. collar 12is carried at one end of the bolt 11 and a standard 13 is slidablymounted in the said collar. The standard 13 is provided at one edge witha set of teeth 14. A worm shaft 25 is journaled for rotation in thecollar 12, substantially parallel with the worm shaft 15. The worm shaft15 has a squared portion 25, adapted to hold a worm wheel 26 againstrotation upon the worm shaft 15, the worm wheel 26 being introducedthrough an opening 27 in the collar 12. This worm wheel 26 meshes intothe teeth llt of the standard 13. It will be seen that by applying awrench or sheath to the squared upper end of the worm shaft 15, thestandard 13 may be raised or lowered, together with the shovel 18,hereinafter described. A foot piece 17 is mounted at the lower end o-fthe standard 13 and carries a cultivator shovel 18 in the usual manner.Thus it will be seen that means are provided for adjusting thecultivator shovel 18 vertically and securing the same in an adjustedposition and at the same time by applying a crank or a wrench to thenon-circular. end 10 of the shaftof the worm 8 and by turning the saidworm that the wheel 7 and sleeve 6 will be rotated and the standard 13may be pitched or positioned at a desired angle with relation to thesurface of the soi Having described the invention what I claim as newand desire to secure by Letters- Patent is z- 1. A standard structurecomprising a block adapted to be applied to a beam,a sleeve journaled inthe block, a worm wheel carried by the sleeve, a worm journaled upon theblock and meshing with the wo-rm the sleeve and restrained againstindependent rotation with relation to the same, a collar carried by thebolt and a standard adjustably mounted in the collar.

2. A standard structure comprising a block adapted to be applied to abeam, a

sleeve journaled in the collar, a Worm Wheel carried by the sleeve, aworm journaled upon the block and meshing with the worm wheel, a boltcarried by the Sleevel and restrained against independent rotarymovement with relation to the same, a collar carried by the bolt, a wormmounted for rotation in the collar, and a standard slidably mounted inthe collar and having at its edge a series of teeth in mesh with thelast named worm.

3. A standard structure comprising a block having an opening adapted tosnugly receive a beam, spaced flanges located at the side of theopening, draw bolts drawing the flanges toward each other and clampingthe block upon a standard, a sleeve journaled in the block, a worm wheelcarried by the sleeve, a worm journaled upon the block and meshing withthe worm wheel, and a standard carried by the sleeve.

In testimony that I claim the foregoing as my own, I have hereto aiiixedby signature in the presence of two witnesses.

EDWARD D. YEATTS.
